First described from Cuba, this Lepiota can be found on the islands of the Lesser Antilles, and we have collected it along the Rio Tuichi in Bolivia and at Las Cruces Biological Station in the southern Talamancas of Costa Rica. It is a very handsome agaric with a tan to cream colored pileus beset with brown lines and detersile scales. The scales are remnants of a universal veil, and are also present at the edges of the skirt-like, white annulus and at the base of the stipe. The pileipellis is an epithelium in which the terminal cells are clavate to globose. The cheilocystidia are clavate to more or less pyriform, and the dextrinoid spores are subfusoid to subcylindric with a truncate base.
